Solar Cells a Few Atoms Thick

Researchers at the Vienna University of Technology have come up with a way to create one-atom thick, flexible, semi-transparent solar cells.  Instead of the graphene often touted as a means toward such an end, however, the scientists have turned to atom-thick layers of tungsten diselenide for their wonder material. Experiments show that ultrathin layers of tungsten and selenium may have properties that would make them applicable even to electric aircraft use – if they can capture a significant amount of energy – or at least as much as thin-film silicon cells can. Graphene has been a popular favorite since its Russian “discoverers” were awarded the Nobel Prize in physics in 2010.  One of the strongest materials, graphene can manage stresses …
